Worst doctor ever. He waited 4 days to address the liter of fluid on my husband's heart. He doesn't visit patients until after 7pm.

Dr. Pieniek has the best 'bedside manner', communicates effectively, and is genuinely compassionate; his staff deserve five stars too (professional, helpful and pleasant).

Dr Pienik is a caring, understanding professional and a fine man to know and have as a Doctor and friend! He is always available when an emergency arises or just to visit for a minute if I see him in the hospital. He really knows the heart and the body and has given me the best care over the years. Trustworthy and willing to go the extra mile for his patients!

Dr Pieniek is not only a good person ,but is a great doctor. I have had several family members die of heart conditions and I needed to find a cardiologist that was very good and that I felt comfortable with. He is the man.

My husband saw Dr. Pieniek prior prior to having major abdominal surgery in 2020 and 8 months later. He's a very kind and reassuring doctor. He and his staff are very professional.

I've been under Dr. Pieniek's care since the summer of 2019. He has a sweet spirit. I never feel rushed in an appointment. He's obviously experienced and knows the cardiology field. All questions are answered fully. He is kind and caring with no trace of arrogance or haughty manner. Highly recommend him. 

Business response:

Thanks for your comment!

Dr. Pieniek goes above and beyond to help his patients! I recently had a situation that was time sensitive. Somehow he was able to schedule me for tests in the hospital the very next morning even though I saw him at 5pm. I appreciate how well and thoughtfully he listens to his patients.
